Good Morning Don, Talked to Wvspec last night, and thought I'd give you the cable # also in case you want to tie your units together. You need the H/B part AS HH GPS handheld connection cable. Sorry we won't see you at Kerr, maybe you can come down for a day trip if they are biting. Snowing like mad here. Doh PS Put my first entry onto the ignore list. Hopefully it will keep me out of trouble. :o
